Infineon Technologies SP30T-00E00-06B

Overview

SP30T-00E00-06B from Infineon Technologies is a fully integrated Tire Pressure Monitoring (TPM) sensor ASIC for SUV and truck applications, combining pressure (100–1600 kPa), temperature (−40 to +125°C), supply voltage (2.1–3.6 V), and optional acceleration (−12 to 115 g) sensing with an embedded microcontroller, on-board EEPROM, dual LF receivers, and ADC signal conditioning in a single P-DSOSP-14-6 package.

For engineers reviewing the SP30T-00E00-06B datasheet, SP30T-00E00-06B pinout, SP30T-00E00-06B application, or SP30T-00E00-06B equivalent, this device supports automotive-grade low-power operation (0.4 µA power-down current), thermal shutdown (102–123°C), ASK-based 125 kHz LF wake-up, and high-reliability measurement in harsh environments - critical for TPMS system design, calibration validation, and OEM compliance testing.

Technical Context

The SP30T-00E00-06B implements a mixed-signal ASIC architecture with dedicated analog front-end channels for pressure, temperature, acceleration, and supply voltage, each digitized via calibrated ADCs (11-bit pressure, 12-bit acceleration, 10-bit temperature, 9-bit VDD). Its dual LF receiver supports ASK demodulation at 125 kHz with 5 mV_p-p sensitivity and <2 ms settling time, enabling reliable low-frequency wake-up from sleep states.

Operation relies on three clock sources: a 2.0 MHz ±10% internal MCLK, a programmable LP oscillator (0.5–4.0 s interval timer), and optional external 3.5 MHz clock input. Thermal protection includes configurable shutdown (ϑ_SHTD) and reset release (ϑ_REL) thresholds, both specified across −40 to +175°C ambient range.

FAQ

What is the maximum pressure the SP30T-00E00-06B can measure?

The SP30T-00E00-06B measures pressure from 100 kPa up to 1600 kPa, with linear behavior confirmed between 1000–1600 kPa per qualification testing. This range supports heavy-duty applications including Class 8 trucks and off-road equipment where standard passenger-car sensors (typically ≤ 900 kPa) are insufficient.

Does the SP30T-00E00-06B include an integrated microcontroller?

Yes - it contains an embedded RISC microcontroller that executes sensor fusion, data formatting, transmission scheduling, and thermal management logic. This eliminates the need for an external MCU in TPMS transmitter designs and enables autonomous operation from power-up to RF transmission.

How does the dual LF receiver improve system reliability?

The dual LF receiver allows simultaneous or redundant reception of 125 kHz ASK wake-up signals, supporting antenna diversity or fault-tolerant configurations. With 5 mV_p-p sensitivity and <2 ms activation time, it ensures reliable triggering even under marginal coupling conditions - critical for consistent TPMS response across vehicle models.

Is the SP30T-00E00-06B qualified for automotive use?

Yes - it is AEC-Q100 qualified and designed for automotive environments, with guaranteed operation from −40°C to +125°C, thermal shutdown protection up to +175°C junction temperature, and qualification across pressure, acceleration, and temperature ranges per ISO 26262-relevant test plans.
